Hi @fipso. UHD removed the get_system_time function from time_spec_t within the last few months. Errors like this can occur when the python templates don't get correctly rebuilt.

The simplest answer is usually to force a rebuild by deleting the gr-uhd build directory, /usr/local/src/gnuradio/build/gr-uhd/ in your case. Then rerun the build and it will regenerate the necessary swig files.

As a side note, having both a source and system install of GNU Radio, or any other package, can lead to confusing linking problems. If you've done that intentionally then you're probably already keeping track of what software is built against one or the other.

[marcusmueller]

I absolutely agree with @dkozel – the problem here is that somehow you're not building with the same headers. As such, it's not a GNU Radio bug, and I'll have to close the issue.

Deleting the gr-udh folder did not work for me. I have only one PYBOMBS prefix "default" in ~/.pybombs/prefix/default. After a rm -R ~/.pybombs/prefix/default/src/gnuradio/build/gr-uhd, and running pybombs install gnuradio, things get re-compiled but I get the same error as previously.

Output from cmd line is the following:

Hi @fipso, I have encountered the same problem. the UHD (v3.13) has removed uhd::time_spec_t::get_system_time() and added uhd::get_system_time(); by running pybombs install gnuradio command，it calls the uhd::time_spec_t::get_system_time(), thus resulting in the problem.

I have managed to solve the bug by modifing the /usr/local/src/gnuradio/build/gr-uhd/swig/uhd_swigPYTHON_wrap.cxx, in which uhd::time_spec_t::get_system_time() is called; here is what i have done:

Replace

result = uhd::time_spec_t::get_system_time();

with

namespace pt = boost::posix_time;                                                                                                                                                                    pt::ptime time_now = pt::microsec_clock::universal_time();
pt::time_duration time_dur = time_now - pt::from_time_t(0);
result = uhd::time_spec_t(time_t(time_dur.total_seconds()),long(time_dur.fractional_seconds()),double(pt::time_duration::ticks_per_second()));

then run the command pybombs install gnuradio, you will do fine.

[fipso]

Thanks a lot. Will try that

[pbybee]

@zbcwilliam your replacement worked to get gnuradio installed for me. Thanks

[wgaylord]

So this seems to still be a problem. Any solutions to it? Like fixing gnuradio to compile with the version of UHD it compiles from source.

[lordcape]

@zbcwilliam thanks!

[gusosborne]

@zbcwilliam thank you sir!!

[syvic]

Same problem and @zbcwilliam workarround works perfectly. Thanks a lot!

[shw1n]

I developed this issue after accidentally installing gnuradio from a repository while already having a working installation, and deleting the gr-uhd build folder wasn't working for me. What did work:

dpkg -l | grep -i uhd

This showed me I had an older version of libuhd-dev installed, after removing that via

dpkg --remove libuhd-dev

I was able to rebuild gnuradio with no issues
